Illusion

The Mer are masters of illusion. Even young Mer can create images that appear to be real until touched. Those with greater skill can make images that move and sound like a living creature.

It is said that true masters of the art can fool the senses of touch and smell as well as those of sight and sound, and even create the appearance of magic where there is none. Learning this level of skill takes hundreds of years.

The most common use of illusion magic is rendering the user invisible. The user creates an illusion of what the space they are in would look like if they were not in it, making them functionally invisible. Skilled Source mages can still sense the use of magic in an area, even if they cannot see the user.
